I bought 2 of these to keep my Bluetti AC200P charged while dry camping, and to charge my Renogy AGM batteries as needed. The panels provide 360-380 watts of input power when in full sun. It's still early Spring, so this may improve. The panels are also much cheaper than similar Bluetti flex panels. However, there are a few drawbacks: 1. Each panel is heavier than my Eclipse folding suitcase, which has 2 glass panels. 2. Connecting the panels in series is an issue at times because the cable length is too short. 3. I have to purchase an extension cable because of the above (#2). 4 Registering the panels was a pain, as the registration site doesn't work. 5. The kickstands are a pain to use. Renogy needs to see what Bluetti is doing with the kickstands on their flex panels, as they are much more convenient to use. Overall, I'm still quite happy with my purchase. Setting up the panels on a daily basis while camping will be a pain, but the cost savings makes up for it. I plan on buying eBikes for my wife and I, so I will also be using these panels to charge those.
